Oscillator control input. Bypass with an external capacitor to slow the oscillator. Since the regulation occurs through switching it is very efficient than linear circuits. The on-board oscillator operates at a nominal frequency of 10 kHz.

Operation below 10 kHz for lower supply current applications is possible by connecting an external capacitor from OSC to ground. The input voltage for the IC is from 1. As mentioned above you only need two capacitors to use this IC. A Simple Negative Voltage. Converter circuit from TC datasheet is shown below:. In the voltage-inverting process, the charge pump capacitor is charged to the input voltage during the first half of the switching cycle and during the second half of the switching cycle, the charge pump capacitor is inverted and the charge is transferred to the output capacitor and load.

For input voltages below 3. Otherwise, the low voltage pin should be allowed to float. Dimensions for TC IC are given below.

These dimensions are for the SOIC package. If you are using different package IC please refer to the TC datasheet. Subscribe to stay updated with industry's latest Electronics components and news.
